Functions

void llvm::finalizeBundle (MachineBasicBlock &MBB, MachineBasicBlock::instr_iterator FirstMI, MachineBasicBlock::instr_iterator LastMI)
 finalizeBundle - Finalize a machine instruction bundle which includes a sequence of instructions starting from FirstMI to LastMI (exclusive).
 
MachineBasicBlock::instr_iterator llvm::finalizeBundle (MachineBasicBlock &MBB, MachineBasicBlock::instr_iterator FirstMI)
 finalizeBundle - Same functionality as the previous finalizeBundle except the last instruction in the bundle is not provided as an input.
 
bool llvm::finalizeBundles (MachineFunction &MF)
 finalizeBundles - Finalize instruction bundles in the specified MachineFunction.
 
MachineBasicBlock::instr_iterator llvm::getBundleStart (MachineBasicBlock::instr_iterator I)
 Returns an iterator to the first instruction in the bundle containing I.
 
MachineBasicBlock::const_instr_iterator llvm::getBundleStart (MachineBasicBlock::const_instr_iterator I)
 Returns an iterator to the first instruction in the bundle containing I.
 
MachineBasicBlock::instr_iterator llvm::getBundleEnd (MachineBasicBlock::instr_iterator I)
 Returns an iterator pointing beyond the bundle containing I.
 
MachineBasicBlock::const_instr_iterator llvm::getBundleEnd (MachineBasicBlock::const_instr_iterator I)
 Returns an iterator pointing beyond the bundle containing I.
 
iterator_range< ConstMIBundleOperands > llvm::const_mi_bundle_ops (const MachineInstr &MI)
 
iterator_range< MIBundleOperands > llvm::mi_bundle_ops (MachineInstr &MI)
 
VirtRegInfo llvm::AnalyzeVirtRegInBundle (MachineInstr &MI, Register Reg, SmallVectorImpl< std::pair< MachineInstr *, unsigned > > *Ops=nullptr)
 AnalyzeVirtRegInBundle - Analyze how the current instruction or bundle uses a virtual register.
 
std::pair< LaneBitmask, LaneBitmaskllvm::AnalyzeVirtRegLanesInBundle (const MachineInstr &MI, Register Reg, const MachineRegisterInfo &MRI, const TargetRegisterInfo &TRI)
 Return a pair of lane masks (reads, writes) indicating which lanes this instruction uses with Reg.
 
PhysRegInfo llvm::AnalyzePhysRegInBundle (const MachineInstr &MI, Register Reg, const TargetRegisterInfo *TRI)
 AnalyzePhysRegInBundle - Analyze how the current instruction or bundle uses a physical register.
